In his near-decade long tenure as chief executive officer, Brian Moynihan has tried to streamline the lender's sprawling operations by cutting jobs, digitizing retail operations and getting rid of crisis-era mortgages, which he inherited as part of its acquisition of Countrywide Financial.

Two years ago, Moynihan pledged to cut expenses to $53 billion by the end of this year and stick to that level until 2020.

Non-interest expense fell 2.4 percent to $13.07 billion in the third quarter, in part due to a 2 percent cut in headcount across businesses.

"Responsible growth, backed by a solid U.S. economy and a healthy U.S. consumer, combined to deliver the highest quarterly pre-tax earnings in our company's history," Moynihan said in a statement.

Net income applicable to common shareholders rose 35 percent to $6.7 billion in the third quarter ended Sept. 30.

Excluding items, the bank earned 67 cents per share, beating the average analyst estimate of 62 cents per share, according to I/B/E/S data from Refinitiv.

Loans in its consumer banking business grew 6 percent to $285 billion. Total deposits rose about 5 percent to $1.35 trillion.

BofA relies heavily on higher interest rates to maximize profits as it has a large deposit pool and rate-sensitive mortgage securities.

Total interest income - the difference between what a lender earns on loans and pays on deposits - rose 6.4 percent to $11.87 billion.

Shares of the company were up 0.7 pct at $28.66 in early trading. (Reporting by Siddharth Cavale in Bengaluru; Editing by Anil D'Silva)
